Warning: Accessing PropTypes via the main React package is deprecated

Not using prototypes directly from React. Not even having a single statement in a whole project like,
import React, { PropTypes } from ‘react’;

Installed PropTypes using npm. using command,
npm install prop-types --save

and

importing PropTypes as,
import PropTypes from ‘prop-types’

then also getting following warning on prompt.

Warning: Accessing PropTypes via the main React package is deprecated, and will be removed in React v16.0. Use the latest available v15.* prop-types package from npm instead. For info on usage, compatibility, migration and more, see https://fb.me/prop-types-docs
